Pyrimido<5,4-b>benzofuran and pyrimido<5,4-b>benzothiophene derivatives. Ligands for alpha1- and 5HT1A-receptors

A number of 3-phenylpiperazinylethyl pyrimido<5,4-b>benzofuran-2,4-dione and pyrimido<5,4-b>benzothiophene-2,4-dione derivatives 5-15 were designed as bioisosters of the previously reported pyrimido<5,4-b>indole-2,4-diones and synthesized starting from the 3-amino-2-carboxybenzofuran and benzothiophene ethyl and methyl esters respectively.They were evaluated for their in vitro alpha1-adrenoceptor and 5HT1A-receptor affinities by radioligand receptor binding assays.All target compounds showed good to excellent affinities for the alpha1-adrenoceptor with Ki values in the subnanomolar range.Some compounds were also good ligands for the 5HT1A-receptor with Ki values in the nanomolar range. 3-<2-<4-(2-Methoxyphenyl)piperazin-1-yl>ethyl>-1-methyl pyrimido<5,4-b>benzothiophen-2,4-dione 15 was the most active derivative in displacing <3H>-8-OH-DPAT from rat hippocampal membranes.There is evidence suggesting that the N1 methyl group of the tricyclic moiety of the title compounds is probably able to undergo a Van der Walls interaction at the 5HT1A-receptor binding site but not at the alpha1-adrenoceptor active site. pyrimido<5,4-b>benzofurans / pyrimido<5,4-b>benzothiophenes / alpha1-adrenoceptor binding / 5HT1A-receptor binding

gamma-Radiolysis of Aqueous Benzothiophene Solutions

gamma-Radiolysis of aqueous benzothiophene solutions saturated with N2O has been studied.In the absence of other reagents, the only products detected are 2- and 3-hydroxybenzothiophene and their corresponding lactonic and ketonic tautomers and a small amount of dimeric species.In the presence of potassium hexacyanoferrate or sodium hydroxide, however, products attributable to hydroxylation at all six available carbon sites are detected and dimer formation is reduced.Analysis of the experimental data suggests that both benzothiophene and its hydroxylation products are efficient scavengers for the radiation-produced OH radicals and that the initial yield of hydroxylation products is equal to that of hydroxyl radicals.Consistent with the electrophilic characteristics of the OH radical, k(OH+C8H6S):k(OH+C8H5SOH)=0.5+/-0.1.All six available carbon sites are capable of forming OH adducts, but the radicals formed by addition to the 4, 5, 6, and 7 positions tend to revert to the original compound or its ion in a neutral or acidic medium.In the case of the adducts formed by addition to the thiophene ring, on the other hand, the 3 position is seen to be favored, possibly as the result of the preservation of the aromatic benzene resonance structure.
